Pod of Orcas Prey on Grey Whale Calf

Info from Licensor: "On April 24, 2017 I encountered a group of five orcas (more showed up later) attacking a mother grey whale and her calf in Monterey Bay, California. I was out scouting for orcas in my boat out of Moss Landing. To my knowledge, this is the first orca predation ever filmed from a Drone on a live mother and calf grey whale. The orcas finally killed the calf grey whale."
